{"id":"CVE-2026-119166","published":"2026-10-31T07:16:36.750","lastModified":"2026-10-31T07:16:36.750","description":"The Welcart e-Commerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.12.5 via the 'member[ID]' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to overwrite any existing Welcart shop-member account's email address and password by supplying that member's numeric ID, then authenticate as that member to achieve full account takeover. The only authentication barrier is a wp_verify_nonce() check against a nonce printed to every unauthenticated visitor on the auto-published New Enrollment Form, meaning no existing account, no WordPress login, and no non-default configuration is required to exploit this vulnerability.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-287"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L3848","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L4470","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L5070","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/usc-e-shop/tags/2.12.5/classes/usceshop.class.php#L5509","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3760784/usc-e-shop","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3760784/usc-e-shop/trunk/classes/usceshop.class.php","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e93b0ebf-576d-48d0-95f7-87135f45980f?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
